Blanket fastener



April 2, 1940. M. LIEBMANN v BLANKET FASTENER Filed Oct. 7, 1939INVENTOR flzoses [2225mm TORNEYS Patented Apr, 2, 1940 UNITED-,- STATESPATENT OFFICE BLANKET FASTENER :Moses Liebmann, New York, N. Y. IApplication time; 7, 1999, Serial No. 298,416: 1 Claim. (01. 24-725)This invention relates .to clamping means for holding blankets, sheetsor bedclothes in place against a mattress, an example of such a devicebeing disclosed in my PatentNo. 2,149,971 dated 6 March 7, 1939. One ofthe objects of. the present invention is to provide a device which willeffectively prevent the blankets from being kicked or thrown'off the bedor otherwise displaced thus leaving the body exposed and unprotected.

10 Another object of the invention is the provision of a clamping deviceof the character described which is especially adapted for use inconnection with mattresses having a rolled top extending along the upperedge of the mattress, the clamp- 15 ing device having means by which thetop roll of the mattress is firmly embraced, and having angularlydisposed jaws which overlie a portion of the top and side of themattress and firmly hold portions of the bed covering against the same.

Another object of the invention is to simplify the structure or. theabove mentioned patent, by constructing the entireclamp from a singlesection of spring metal, whereby the manufacturing 25 cost is greatlyreduced and economy in production is secured; wherein also the size ofprojecting elements is reduced and a more effective spring clampingaction of the jaws on the roll top of the mattress is attained.

More particularly, the invention contemplates the provision of a singlesection of spring sheet metal formed with a substantially cylindricalspringportion which fits over and closely conforms to thecross-sectional shape of the roll 35 formed on the edge of the mattress,and a pair of the entire clamp is actually produced from a sin- I glepiece of metal.

In the accompanying drawing, wherein several illustrative embodiments ofthe invention are shown, Fig; 1 is an end view of the clamp in positionon the roll top of a mattress, the roll top of. the mattress and aportion of a blanket extending thereover being shown in. section;.Fig. 2is a plan view of the clamping device; Fig. 3 is 55 a section view onthe line 3-3 of Fig. 2, looking in thendirection of .the arrows; andFig. 4 is "a sectional view through a modified construction. Withreference to the structure shown in Figs. 1 to 3 inclusive, l0 indicatesthe rolled edge of a mattress I, said rolled edge being usually formed 5along the top of the mattress and it extends completely around the same.superposed upon the mattress in the conventional way is a blanket,sheet, quilt or other bedclothing indicated at l2 which may be securelyand neatly held in position over the mattress by means of a plurality;of clamping devices 13, one of which is shownin the drawing. v

The clamping device I3 is preferably formed from a single section ofspringy, resilient sheet metal and it includes a substantiallycylindrical spring section I! from which. extends a pair of angularlyprojecting jaws M, which are shown in their normal closed position inFig. 3. The tendency of the cylindrical springportion is to force saidjaws toward one another so that in their normal closed position the jawscontact only at the points where they join with the cylindrical springportion. As seen in Fig. 2, the jaws are longer than the spring portionI! and thus when the clamp is placed in position over the rolled edge ofa mattress, they overlie a considerable portion of the rolled edge andhold the bed clothing closely against the'side and top of the mattress,as clearly shown in Fig. 1'. The free ends or edges of the jaws areturned outwardly, as indicated at l5 to provide stiffening flanges whichnot only add stifiness and rigidity to the jaws, but also provide smoothedges thereon which cannot possibly cut into and damage 36 the bedclothing or the mattress.

To permit the clamp to be readily placed on and off the mattress, Iprovide finger-engaging lugs I6 which are formed by being cut out of thebody of the cylindrical spring portion and then 40 forced outwardly orradially so that they may be easily gripped between the fingers of thehands, as indicated in dotted lines in Fig. 1, and moved in thedirection of the arrows therein shown, to spread the jaws apart. In useit will be noted 5 that the jaws l4 rest flatwise against the top andside respectively of the mattress and hold the blanket l2 thereagainst.It will also be noted that while these jaws press the blanket'firmlyagainst the top and side of the mattressthey have'no parts tending topenetrate, cut or bite into the blanket or mattress so that thepossibility of causing damage thereto is wholly avoided.

It will be additionally noted that the entire clamp is made from asingle section of sheet metal so that its manufacturing cost isnegligible, and that due to its unitary construction it conforms closelyin shape to the portion of the mattress which it embraces and lacks theprojecting elements often found in prior devices which render themdifiicult to place on and remove, and which often scratch or otherwisedamage the bed.

In the modified structure shown in Fig. 4, finger-engaging projectionsl3 are shown which are made slightly longer than those indicated at ISin Figs. 1 to 3 inclusive. The projections or lugs l8 are doubled backas indicated at I!) so that they may be moved toward one another bybeing compressed by the fingers of one hand, whereby manipulation of theclamp is somewhat simplified.

It will be understood that the device may be made of any suitablematerial, shape and size to suit various requirements and that one ormore of the devices may be employed at the edge of the mattressaccording to the requirements necessary to hold the bed coveringsecurely and neatly in position.

What I claim is:

A device for holding bed clothing to the rolled edge of a mattresscomprising, a clamp having a cylindrical spring portion, the ends ofsaid portion being bent laterally and sharply angularly to form a pairof fiat faced jaws, said jaws extending angularly with respect to oneanother and being normally distended away from one another at theirouter ends, said jaws having their outer edges bent sharply angularly tothe plane of th jaws to provide stiffening flanges along said edges,said jaws being longer than the cylindrical spring portion and. beingformed integrally with the cylindrical portion and being respectivelyadapted to overlie the top and side of a mattress, and finger-engaginglugs cut out of the cylindrical portion for manually moving the jawsaway from one another against the tension of the cylindrical portion.
